Unusual Co-operation Between Species In Competition For Scarce Vegetation In Northern Mountain Areas
2013-04-25 15:44:10

Who would have thought that two very different species, a small insect and a furry alpine mammal, would develop a shared food arrangement in the far North? University of Alberta researchers were certainly surprised when they discovered the unusual response of pikas to patches of vegetation that had previously been grazed on by caterpillars from a species normally found in the high Arctic. U of A biology researcher Isabel C. Barrio analyzed how two herbivores, caterpillars and pikas,...

University of Alberta researchers were certainly surprised when they discovered the unusual response of pikas to patches of vegetation that had previously been grazed on by caterpillars from a species normally found in the high Arctic. U of A biology researcher Isabel C. Barrio analyzed how two herbivores, caterpillars and pikas, competed for scarce vegetation in alpine areas of the southwest Yukon. The caterpillars come out of their winter cocoons and start consuming vegetation soon after...

Exciting Life Cycle Of The Brazilian Leaf Miner
2013-04-19 13:25:23

Pensoft Publishers A new species of leaf miner from the important family Gracillariidae has been recently discovered in the depths of the Brazilian jungle and described in the open access journal Zookeys. The Gracillariidae family is an ancient one with fossils dating back its origins to around 97 million years. Among the leaf miners of this family there are some species with significance as economic factors as well as agricultural pests. The new species, Spinivalva gaucha, is associated...

Monarch Butterflies Rely On Landmarks In Order To Find Their Way
2013-04-09 12:37:42

Alan McStravick for redOrbit.com - Your Universe Online In an article written for redOrbit last month by Michael Harper, the overall population of the Monarch butterfly was predicted to be significantly lower than in years past. It is believed this decline is due to the combination of expanded farmlands and the steady increase in temperature in their migratory corridor. A new study, led by researchers from the University of Guelph, focused on the migratory corridor followed by these...

Expect To See Fewer Monarch Butterflies This Spring
2013-03-14 18:12:32

Michael Harper for redOrbit.com — Your Universe Online Every year, hoards of Monarch butterflies begin their epic journey from Mexico through the hills of Texas to all points north, sometimes as far as Canada. Unfortunately, there will be fewer butterflies to take this journey during the coming months. It´s a trend that has been ongoing for about seven years or more and, according to Omar Vidal with the Mexican branch of the World Wildlife Fund, high temperatures and expanding...

Butterfly Evolution Can Also Be Driven By Spiders
2013-03-13 05:09:24

April Flowers for redOrbit.com - Your Universe Online Butterflies are vibrant and colorful insects, with colorations designed to deflect predators. A new study from the University of Florida reveals that some of these predator driven defenses may be caused by enemies one-tenth the size of the butterfly. Since Darwin sailed on the Beagle over 150 years ago, scientists have theorized that the main influence on the evolution of coloration in butterflies came from large predators such as...

Monarch Butterflies Won't Migrate North Unless They Can Chill Out First In Mexico
2013-02-22 10:09:45

April Flowers for redOrbit.com - Your Universe Online Millions of monarch butterflies from across the eastern U.S. begin a southward migration each fall to escape the frigid temperatures of the northern boundary of their range. They travel up to 2,000 miles to reach an overwintering site in a very specific grove of fir trees in central Mexico. A new study from the University of Massachusetts Medical School (UMass) suggests the butterflies require the exposure to coldness in the...

Lepidoptera Species Found In Jamaica

April Flowers for redOrbit.com - Your Universe Online A study describing a new species of Lepidoptera found in Jamaica's last remaining wilderness was recently published in the journal Tropical Lepidoptera Research by a team of scientists from the University of Florida. The new species belongs to the skipper family of butterflies. This is the first new butterfly discovered in Jamaica since 1995 and scientists hope that the native butterfly will encourage conservation of the Cockpit...

When herbivores such as caterpillars feed, plants may "call for help" by emitting volatiles, which can indirectly help defend the plants. The volatiles recruit parasitoids that infect, consume and kill the herbivores, to the benefit of the plant. However, such induced plant odors can also be detected by other organisms. A new study published November 27 in the open access journal PLOS Biology shows how secondary parasitoids ('hyperparasitoids') can take advantage of these plant signals to...

The Plutella xylostella is often referred to as the Diamondback or Cabbage moth. This species is has a brief lifespan of only 14 days and is thought to have originated in the Mediterranean region of Europe, but has since dispersed across the world. This species is capable of reproducing quickly and can travel great distances. Diamondback are considered serious pests in warmer climates when the absence of a harsh winter prevents their eggs from being destroyed. The moths are resistant to...
